The mum-of-one looked absolutely in-credible in a pair of billowing bottoms that boasted killer kick flares, a sheer snake-print overlay and a high-waistband that drew attention to her eye-popping hourglass shape.
Billie - who was joined by former Geordie Shore star Charlotte Crosby and Made In Chelsea's Binky Felstead, both also launching new transeasonal collections - stood out from the crowd in a ruffle-adorned Bardot top in powder blue that served to accentuate her gorgeous Majorca glow.
As always, her beautiful blonde locks were styled into the most p-e-r-f-e-c-t waves and she was all smiles as she sashayed past the paparazzi and into a secret venue in Soho.
Billie recently announced that she would be taking a break from The Only Way Is Essex after six years of starring in the show.
Gorgeous Ms. Faiers is just one of the few original TOWIE stars still on the ITVBe show but has apparently decided to call it a day...for 2016 at least.
A Lime Pictures spokesperson recently told us: "Billie has recently made us aware that she would like to prioritise family life and little Nelly for the rest of the year.
"We are in full support of this decision and will continue discussing with her how best to move forwards. Billie is a much-loved and valued member of the TOWIE team and we are happy she wants to continue working with us."
We'll miss ya, Bill!
